Product Details:
This electronic tube preamp has a rich mid-range, warm sound, elasticity, strong air feel, and can be heard for a long time without getting tired! The effect of replacing different brands of electronic tubes varies significantly.
1:) 50W pure copper wire power transformer and 10H 45mA high inductance choke coil.
2:) 6Z4 electronic tube rectification, combined with CLRC filtering circuit, with small ripple and quiet background.
3:) Copper foot metal film precision resistor+carbon film resistor, with a strong electronic tube flavor.
4:) Japanese ALPS 16 potentiometer.
5:) High quality 1.2mm thick iron spray painted chassis.
6:) Three pairs of paired high-power field-effect transistors are connected in parallel for current expansion output, ensuring driving force.
7:) Solid aluminum knob with dial, feels great to the touch.
